To all whom it may concern Be it known that I, WILLIAM CARL HUEB- mm, acitizen of the United States, residing at Buffalo, in the county of Erieand State of New York, have invented a new and useful Improvement inUniversal Printing- ,Machines, of which the following is aspecification.

This invention relates to universal printing machines for producingprints from a primary printing surface in a desired location, positionor arrangement on a secondary printing surface, proof sheet or otherprintreceiving surface.

Machines embodying the, lnventlon are especially adapted for producingsecondary printing surfaces on which prints from several different kindsof rimary printing surfaces, such, for examp e, as wood cuts,,copperplates, steel engravings, drawings on stone, type, and lithographicengravings, or photographic negatives or positives, are assembled in adesired arrangement or grouping; also for printing a plurality ofduplica'te impressions in prescribed locations and positions on asecondary printing surface, or other print-receiving surface; and forbuilding up designs on printing surfaces, or other surfaces, byrepeating thereon in different required locations and positions,impressions from a design unit on a primary printing surface. Thesecondary printing surface can be a plate, stone or other surfaceadapted to be used for mechanical printin The object of the invention isto provi e an efficient, practical and desirable printing machine whichis adapted to be quickly, easily and accurately ad'usted and rapidlyoperated for producing iiferent desired results of the nature mentioned.

Briefly stated, the machine comprises a bed or platen for supporting theprinting surface, a bed or platen for supporting the print-receivingsurface, one in advance of the other, and an offset or transfer cylinderprovided with a suitable offset blanket or surface, which cylinder iscaused to roll first over the printing surface to take an impressiontherefrom and then over the print-receiving surface, for producingthereon a print'from said impression. One of the beds or platens isprovided with a holder which is adjustable with reference to the offsetcylinder to enable the impression to be made on the cylinder in anylocation lengthwise and circumferentially thereof and in any angularposition necessary to reproduce the subject in the desired location andangular position on the print-receiving surface. The offset cylindertravels over the platens on a supporting track, and means are providedfor raising the platen to place the is adapted to be adjusted afterreceiving theimpression, both axially and circumferentially, forrepeating the prints in any desired location, arrangement or grouping onthe print-receiving surface.

Like reference characters refer to like parts in the several figures.

A represents the stationary main frame of the machine which can be ofany suitable construction, that shown being of enerally rectangularshape and of skeleton orm.

B and G represent, respectively, the primary and secondary beds orplatens for supporting the primary printing plate or surface and thesecondary printing or print receiving surface. These platens arearranged one in advance of the other with respect to the direction oftravel of the offset cylinder and are movably mounted on the main frameand provided with means for adjustin th'em vertically to place theprinting an print receiving surfaces in correct printing relation to theofiset cylinder and for moving them quickly to and fromthis positionwhen making prints.

In the machine illustrated (see particularly Figs. 2,,8'Qand $3 theplaten B is provided at opposite si es with guide ribs 6 .which slidevertically in adjustable guide ways b 0n the main frame, and issupported and adjusted vertically by two screws D D, secured to theplaten and working in rotatable screw sleeves or nuts, which are'ournaled and held from endwise movement in suitable hearings in crosspieces d of the main frame.

d, Fig. 8, indicates one of the screw" sleeves, and d the bearingtherefor. The two screw sleeves d are connected by bevel gears (i d to ashaft (Z by which they are caused to turn in unison. This shaft (i issuitably journaled on the main frame and is connected by bevel gears d dto an operating shaft D which is suitably journaled on the main frameand is provided at the front of the machine with a wheel or handle atfor turning it. The secondary platen C is. adjusted by screws (1 work1ngin screw sleeves or nuts d which are similarly geared to an operatingshaft D The platens B and C can thus be independently adjustedvertically by turning the operating shafts D and D to place the printingand print receiving surfaces, of whatever kind, supported thereby in thesame horizontal plane, or.in other necessary rinting relation to theoffset cylinder. eans are also provided for operating the shafts D D, toquickly move the platens to and from the printing position relative tothe oflset c linder for making the. impressions after t e platens haveonce been adjusted for a particular piece of work in the manner abovedescribed. These means are preferably constructed as follows:

E, Figs. 1 and 4-7, represents a hand lever which is fulcrumed on aneccentric pivot e on a shaft e which is suitably journaled in the frontportion of the main frame.

The hand lever E is provided, in a slotted portion thereof through whichthe operating shaft D passes, with a gear segment e adapted to mesh witha pinion e secured to the operating shaft, 1), so that said shaft can beturned by swinging the lever E. By turning the fulcrum shaft e'in onedirection or the other, by a handle a projecting from the shaft, thegear segment on the lever E is moved into or out of mesh with the pinion0 The fulcrum shaft istprovided with a latch 6 adapted to engage in oneor the other of two notches e, Fig. 7, inthe shaft bearing for holdingthe lever falcrum. stationary with the toothed segment either in or outof mesh with the pinion e After the platen has been adjusted to securethe proper printing relation between the printing surface thereon andthe ofiset cylinder, by turning the shaft D, as above explained, and themachine is ready for printing, the hand lever E is raised until itis-arreste'd by engagement with a fixedstop e on the main frame, and thefulcrum shaft e is turned to place the gear segment in mesh with thepinion 6 Then by loweringthe hand lever, the operating shaft D will beturned in-a direction to lower the platen away from the ofiset cylinder,and by again raising the lever E until arrested by the stop 6 the platenwill be returned to the printing position. Thus by the simple operationof the hand lever the printing surface can be quickly lowered repeatedlyfrom and returned to exactly the same printing position. en it isneces-"- sary to adjust the platen for difierent work, the hand lever Eisdisengaged from the operating shaft D by turning the fulcrum shaft 6,and the operating shaft D can then be turned, as required, to secure thenecessary adjustment of the platen B.

The teeth on the wheels and railsare preferably made obhque to reduce tothe minimum the-lost motionbetween the wheels and the track and insure a positive motion of thecylinder without slipping or shifting on the track, so that a givenpoint on the cylinder will register with the same points on the platenin the successive traverses f the cylinder. beveled faces of the wheelssustain the weight of the cylinder and reduce the wear on the teeth ofthe wheels and the track. Theends of the cylinder carriage depend belowthe track and are provided with rollers- 9' adapted to roll againstdownwardly facing rails g on the front and rear of .the main frame toprevent tliecvlinder from lifting oil of its guide track. These rollersf are preferably journaled inboxes 9, Fig. l, which are adjustable forpreventing any play between the cylinder and the guide track.

The ofiset cylinder is driven for propel: ling it along the track,preferablyv by an electric motor H, see Fig. 3, which is supported onone end of the carriage G. The armature shaft of this motor is connectedby The any suitable gearing h, Fig. 3, to a wheel k,

secured to the adjacent journal of the ofiset preferably employed, butthe cylinder can 7 be mounted and driven in othersuitable ways, andother securing means for the blanket can be used.

Theplaten C shown is also provided with suction means for holding papersheets thereon when the machine is to be usedfor printing directly onpaper. For this purpose the platen is provided with a marginal suctionduct or chamber 2', see Figs. 10, 26 and 27, and the end edges of theplaten are beveled at z" and provided with perforations whichcommunicate with the end portions of the suction duct. A pipe i connectsthe duct 2' with a vacuum pump or other means for exhausting the air.from the duct. The flanged upper bar 71 of the clamp 1 serves as a gagestrip for the sheets. The sheets are placed on the platen with one edgeagainstthe gage strip i and a suitable controlling device, not shown, isactuated for producing the suction whereby the ends of the sheet will bedrawn down against the perforated edges of theplaten, so as to'hold thesheet smoothly and firmly on the platen.

K, Figs. 3 and 19-24, represent-sen -ad-' justable holderfor securing aprinting surface on the primary platen and adjusting the same, as may benecessary to place. the impression therefrom in a required location andposition on the oflset cylinder. This holder maybe of any constructionadapted to give the necessary adjustments. As shown, the holdercomprises a base plate K which is adapted to be removably secured on theplaten, a pivoted frame or plate K which is adapted to be rotatablyadjusted on the of mesh with the toothed segments.

This screw is is provided at one end with a knurled head forturning it and at the other end with a thread adapted to mesh withtoothed segments is k on the opposite ends of the pivoted plate. Thescrew is pivoted by a bearing block 70 in a cavity in a slide block 71:,so that the screw can be swung into and out of mesh wit-h the toothedsegments. The slide block is is arranged to slide in a curved guideway70 on the base plate K concentric with the center of the pivoted plate KThe slide block is can be moved to any desired position in the guide wayk and be secured in such position by tightening a set screw 7c carriedby the block. The adjusting screw extends through a hole in a fingerpiece k which is movably secured on the end of the block In by a screw70 passing through a slot in the finger piece. The finger piececotiperates with its securing screw is to retain the adjusting screw inthe position to which it is moved either in or out When it is desired toadjust the pivoted plate K it, is turned on the base plate bv handapproximately to the desired position.

The screw is adapted to be held inengagement with the rack by a set screw Z, or other holding device. Whenthe adjusting screw is disengaged from the toothed rack the slide K canbe moved to any desired position on the pivoted plate K and then byengaging the screw with the toothed rack and turning the screw, theslide can be adjusted accurately to the desired position, as indicatedby a suitable pointer Z on the slide, cotiperating with a graduatedscale on the adjacent flange of the pivoted late.

The rotatable top p ate K is adjusted on the slide plate, in a similarmanner, b an adjusting screw Z, Fig. 19 providedzi ph a thread adaptedto engage teeth on the-edge of the top plate. The adjusting screw l ispivoted by abearing 1: in a recess in the slide K and is adapted to beswung into and accurately adjusted by moving the adjusting screw intoengagement with the toothed rim of the top plate and turning theadjusting screw until a pointer l on the table co- .raduated scale onthe slide K indicates t e required adjustment. By rotatably adjustinthe-pivoted plate K on the base plate K and adjusting the slide Kradially on the pivoted plate, the primary printing surface on the topplate K can be moved to any 'desired pos tion, within the range of theholder, bot-h lengthwise and transversely of the platen, so as to placethe impression in any required location, lengthwise andcircumferentially on the ofi'set cylinder, and by adjusting the topplate K rotatably on the slide K the primary printing surface can beturned to any required angular position. The holder K constitutes anattachment which can be readily removed from the platen when it is notrequired and again placed in position for use thereon. For work in whichthe primary printing surface does not have to be adjusted to difierentpositions on the platen, the holder is removed and the printing surfaceis secured directly on the platen by an known or suitable means, or whena thin exible printi g late is employed, this is secured and str tc edon the platen by the clamps before described. M represents the suplemental oflset cylindex" which, like t e'rmain ofiset cylinder, isarranged to roll over the primary and secondary platens for transferringan impression from the printing surface to the print receiving surface.The supplemental oflset cylinder is, however, shorter than the maincylinder and is arranged, as shown in Figs. 11-14, to be adjustedtransversely of the platen to any desired position, and alsocircumferentially with respect to its supporting wheels, so that animpression on the cylinder can be applied to any desired portion of theprint receiving surface. The offset blanket m is preferably secured onthe cylinder by securing and stretching devices m similar to thoseemployed on the main offset cylinder. The supplemental cylinder isconnected to ooved and toothed sup orting and propel ing wheels N and Na apted to roll on the supporting track for the main oflset cylinder.These wheels are rovided with suitable journals n seate in bearings inthe ends of a carriage n which is pre erably similar in construction tothe carriage for the main ofl'set cylinder and the cylinder is driven bya motor (not shown) supported by the carriage and connected by suitableears n n to the wheels N.

The transverseadjustment is indicated by a disk secured to the end of the screw andprovided with an index coiiperating with a surrounding scale which issecured to the adjacent end of the carriage n. The supplemental ofi'setcylinder can be constructed and mounted in any other suitable way whichpermits it to be adjusted circumferentially and transversely relative toits supporting wheels N N, and any other suitable means can be employedfor indicating the adjust- In the of the machine the main oflsetcylinder F is used when a large subject is to be reproduced, and indoing work which does not require endwise adjustment of the c linder.-After the printing surface and t 0 print receiving surface have beenproperly adjusted and registered on the primary and secondary platens,and the platens adjusted by means of the screws D D as before explained,to place the printing and print receiving surfaces in correct printingrelation to the offset cylinder, the driving motor for the cylinder isstarted and the cylinder is thereby caused to roll on the supporting.track over the platens. By actuatmg the hand lever E the primary platenis raised, as before explained, to move itinto position for the cylinderto receive an impression from the printing surface on the platen. Thesecondary platen is raised in a similar manner by actuating its lever Eto place it in position for the impression to be printed on the printreceiving surface carried by this platen. The platens are then loweredby means of their actuating levers and the drivin motor for theofl'setcylinder is reversed t or returning the cylinder. When it is desired toreproduce a small subjeet, or to place successive impressions indifl'e'rent locationsor positions on the print receiving surface, thesupplemental offset cylinder M is used, and if the adjustment requiresit, the primary printing surface is" secured on the adjustable holder Kand placed in the required position by the adjustment of the holder.After the supplem'ent'al cylinder has been rolled over the primaryprinting surface to take an impression therefrom, it can be adjustedeither circumferentially or transversely, or both, as re quired to"place the print in the required position onthe print receiving surface.By appropriate adjustments of the supplemental ofiset cylinder, or ofthe holder K, or both, successive impressions from the primary rintingsurface can be placed in any des'i' arrangement or grouping on the printreceiving surface. Ina similar manifiipressi ons fromdifferent primaryprinting surfaces can be placeujqr' grouped device comprises an openrectangular framem of any suitable construction provided with a glass ortransparent plate which 1s supported by the frame above and close to theprinting or print receiving surface. The opposite side bars of the framemare grooved to rest and slide on the track rails for the offsetcylinder, so that the register-' ing device can he slid on the trackfrom a position over one platen'to a position overv the other, and a pinm on the front of the "frame m is adapted to be inserted in holes in themain frame to hold the registering device in'correspond-ing positionsover the primary and secondary platens. One of the holes for the pin mis shown at m Fig. 1. The registering glass or plate, shown, is providedwith cross lines m and with a circle m concentric with the intersectionof the cross lines, and the corners of the plate are cut away andopenings m formed in the plate, so that the printing and the printreceiving surfaces beneath the plate can-be reached to shift them on theplatens to place suitable register marks thereon coincident with theregister lines on the registering plate. Thus by first placing theregistering device in position over the primary printing surface andregistering this surface with lines on the registering plate and thenmoving the registering device into position over the print receivingsurface and shifting this' surface to a corresponding position withreference to the registering device, the printin and printreceivingsurfaces can be readily placed in exact registration or relation to eachother and to the OE- set cylinder. After the, printing and printreceiving surfaces have been properly registered the registering deviceis removed from the machine. It is provided for this. purpose at-itsends withha'ndles m. for lifting it.

Means are provided for sustaining the ofi'set cylinders with theirsupporting wheels clear of the guide track, so that the cylinders can berevolved. in a stationary position without horizontal movement on thetrack for cleaning the ofiset blankets and also to enable the maincylinder to be turned, as may be necessary for an impression to be madein a desired position circumterentially thereon. For this purpose. thetrack rails g g are previded at the end.

menace of the machine beyond the primary platen B with short railsections R" which are adapted to be lowered out of engagement with thesupporting wheels of the main oliset cylinder while the cylindercarriage is stationarily supported with the wheels over the gaps thusmade in the track rails. Similar movable rail sections R are provided atthe other end of the track for enabling the supplemental offset cylinderalso to be revolve while held in a stationary position.

The rail sections R are carried by slides 1', Figs. 15 and 16, which aremovable vertically in suitable guides r on the inside of the front andrear walls of the main frame. The lower ends of the slides are held bysprings 1- against fixed disks 1' on ashaft 4 which is journaled inhearings in the front and rear walls of themain frame and is provided atits front end with a crank handle 4* for turning it. This shaft is alsoprovided with fixed disks '1' beneath the ends of the cylinder carriageG for supporting the carriage. The disks r? and r are of se mentalcircular shape the flat portions of the disks r being diato the flatportions of the other disks r. In the position of the shaft r, shown inFig. 15, the circular edges of the disks 7* support the rail sections Rin the line with fixed portions of the rails, while the flat edges ofthe disks 1' are uppermost. The wheels y then rest on the movable railsections R and support the ofi'set cylinder. Byturningthe shaft 1'one-half revolution the circular edges of the, disks 1' will engage theends of the carriage G and support the cylinder while the flat edges ofthe disks 1 being uppermost, the movable rail sections R will be loweredout of engagement with the cylinder supporting wheels by the springs TThe carriage G will then be stationarily supported and the offsetcylinder is free to be turned therein as may be desired for adjusting.its position relative to the platens, or for cleaning the blanket. Thewheels of the ofiset cylinder can thus be disengaged from and engagedwith the supporting track without raising or shifting the ofisetcylinder by simply turning the shaft 1* onehalf revolution. Thesupplemental ofiset. cylinder is adapted to be similarly supported clearof the guide track bymoving it to a position in' which its wheels N Nreston the movable rail sections R and lowering said rail sections byturning a shaft 1". v
